STRAW-STACKER FOR TH RASHING-MACHIN' ES.

SPECIFICATION forming part of Letters Patent No. 289,462. dated December 4, 1883.

Application filed June 13, 1883.

To all whom it may concern.- Be it known that we, DUDLEY D. SPRAGUE, of California, in the county of Moniteau and State of Missouri, and PEARLEY J. SPRAGUE, of Higbee, in the county of Randolph and State of Missouri, have invented a certain new and useful Improvement in Straw-Stackers for Thrashing-Machines, of which the following is a full, clear, and exact description, ref- IO erence being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a side elevation of our improved stacker for thrashing-machines; Fig. 2, an

I 5 enlarged top view; Fig. 3, a vertical section taken on line 3 3, Fig. 2; Fig. 4, an enlarged side view; and Fig. 5,. a section on line 5 5, Fig. 3.

The object of our present invention is to construct a cheap and effective stacker; and to this end our invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, Arepresents the 2 5 rear end of a thrashing-machine, to or near which is secured a base, B, suspended from or resting upon a circular track, 0. lVe have shown the base suspended from the track by means of hangers G, which are secured to the base and hook over the track, so that the base can be freely moved or turned horizontally, the hangersinoving on the track andwe have shown the track secured to the machine by means of folding beams D D, to the outer ends 3 5 of which the track is secured, which are connected to the machine at D by means of pivotbolts or a rod, as shown, andwhose inner ends eomeagainst stops E E when the beams are in their normal positionsecured to the machine. 40 (See Fig. 1.) The beams are thus self-supporting, and can be turned up to allow the base to be folded in transportation. ,The base.

has a closed bottom and also closed sides and back, as shown, and to its forward portion is hinged the elevator-frame F. The straw,

850., from the machine fall through the circular track to the base. We have shown the elevator-frame secured to the base by means of brackets G, in which the ends of a roller,

(No model.)

H, are journaled, and beneath which roller the raddle-belts pass.

I represents an apron secured to the base and extending onto the elevatorframe, for the purpose of closing the space between them, and as it is not secured to the elevator-frame it does not interfere with the stacker being raised and lowered independently of the base.

J represents the endless raddle-belts, having an undershot motion, as indicated byzthe arrows, and provided with spikes or. pins J. They pass around the roller K on the upper end of the stacker, under a roller, L, supported by the brackets G or other suitable means, around a driving-roller, M, located in the rear portion of the base, and under the above-mentioned roller H. The roller M is turned to operate the raddle-belts by means of belt-connection with gearing mechanism beneath the base,which receives power from the thrashing-machine; or the roller maybe turned in any other suitable way; or one of the other rollers may be the driving-roller, if desired. The rollers preferably havecollars, as shown, to receive the belts, and those on the roller or shaft L have central slots, to allow the passage of the spikes or pins J. (See Figs. 2 and 5.) Thus with our improved arrangement the raddle-belts take the straw, 830., directly from the machine, it passing beneath the roller M, which compresses it, dispensing with an intermediate carrier, the base allowing the elevator-frame to be moved horizontally to distribute the straw.

The base may be provided with a horizontal board,B, for supporting the upper parts of the belts, (see Figs. 2 and 3,) and which would prevent the straw, Ste, falling through between the belts, compelling it to be carried around beneath the roller M.

We claim as our invention-- 1. The combination, in astacker, of a base, an elevator-frame hinged to the rear endthereof, and a raddle or straw-forwarding device extending from the front end of the base to the delivery end of the elevator-frame.

2. The combination of a thrashing-machine, a base at the rear end thereof, and an elevator-frame secured to the rear of the base,

having a raddle extending from the machine I 5. The combination of a thrashing-machine end of the base to the delivery end of the ele- I having stops projecting outwardly from the vator-frame, as set forth.

3. The combination of athrashing-machine, 5 a circular track secured to the rear end thereof, a base supported by said track, and an elevator-frame secured to the rear of the base, having a raddle extending from the machine end of the base to the delivery end of the elevator-frame, as set forth.

4. The combination with a thrashing-machine and an elevator-frame, of a base intermediate of., the machine and the elevatorframe, a roller journaled in the machine end of I5 the base, a roller journaled in the outer end of the elevator-frame, a roller by Which the elevator-frame is hinged to the base, a circumferentiallygrooved roller above the hingeroller, and spiked carrying-belts extending 20 around the rear and outer rollers and beneath the grooved and hinge rollers, as set forth.

sides thereof, a circular track having arms projecting on each side of themachine, and 25.

hinged thereto to permit the track to be raised against the end of the machine, and an elevator hinged at the rear end of the track, the track being held in operative position by means of its hinges and stops, as set forth.

In testimony of which We hereunto set our hands in the presence of two Witnesses.
